Abstract: A tuyere for the injection of both a refining gas such as oxygen into a melting or refining vessel, and a fluid protective medium such as a hydrocarbon gas or a liquid surrounding the injected refining gas, in which there is a solid center in the pipe through which the refining gas is suplied so that the refining gas enters the refining vessel as an annulus around which the protective fluid is disposed. The tuyere is installd in the refractory lining of the refining vessel and the fluids passing into the vessel through the tuyere are proportioned so that burning back of the tuyere and erosion or wear of the lining take place at the same rate. The protective medium cools the tuyere and avoids reactions between the refining gas and the tuyere material.

Abstract: PHB 32,541 A radio interferometer system for determining the angle of incidence of signals received from a remote radio source comprises a substantially linear series of n + 1 (n ? 2) aerial elements.  The two outermost aerial elements form a first pair to which a digital phase discrimator is coupled to measure accurately but ambiguously a first phase difference between signals received by this first pair.  Digital logic means are used to resolve the ambiguity of this first phase difference measurement to produce an accurate and unambiguous measurement with means connected to the digital logic means to produce an indication of the angle to be determined.  Each two successive aerial elements form successive further pairs to which further digital phase discriminators are coupled to measure unambiguously further phase differences between the signal received by these further pairs.  Digital logic means are arranged to add these unambiguously measured further phase differences to produce a sum and to compare this sum with the ambiguous first phase difference measurement to produce the accurate and unambiguous measurement.

Abstract: The demodulator produces an inphase digital reference signal having the form cos A by means of an analog-to-digital converter and a quadrature digital reference signal having the form sin A by means of an N-stage shift register coupled to the converter. An inphase digital FSK signal having the form cos B is provided by a second analog-to-digital converter and a quadrature digital FSK signal having the form sin B is produced by a second N-stage shift register. A first read only memory responsive to the inphase and quadrature digital reference signals and the inphase and quadrature FSK signals produce an inphase code signal and a quadrature code signal for estimating the value of (B - A). A first M-stage shift register delays the inphase code signal and a second M-stage shift register delays the quadrature code signal. A second read only memory responsive to the inphase and quadrature code signals and the delayed inphase and quadrature code signals determine whether the value of (B - A) is increasing or decreasing. Logic gate means coupled to the two outputs of the second read only memory determines whether a first given code is detected more frequently than a second code and vice versa. A low pass filter coupled to the logic gate means averages the difference between the first and second given codes to produce a high voltage for a "mark" and a low voltage for a "space.

Abstract: A seat belt retracting and winding device is provided with a driving wheel rotatable in unison with a seat belt winding shaft, ratchet means consisting of a ratchet wheel and a catch, a cam disk and a catch holding disk adapted to maintain the catch in position in engagement with or disengagement from said ratchet wheel. Strong and weak springs are encased within the ratchet wheel and the driving wheel, respectively, and are interconnectable in series to each other. When the seat belt is paid out and fastened, the catch holding disk and the catch cooperate with each other to lock the ratchet wheel so that the strong spring is disconnected from the weak spring and consequently unpleasant restraining force on a driver or occupant may be reduced or relaxed. On the other hand when the seat belt is unfastened, the rotation of the winding shaft in the opposite direction causes the cam disk and the catch holding disk to cooperate with each other so as to release said locked ratchet wheel for free rotation so that the strong spring is drivingly coupled to the weak spring and consequently the positive and complete retraction of the seat belt may be ensured.

Abstract: Silica aerogel in the form of a substantially crack-free, preferably transparent block is described, together with a method for the preparation of such aerogel and use thereof in solar panels. The preparation is effected by means of hydrolysis of a tetraalkoxysilane, preferably tetramethoxysilane, in an alcohol, preferably methanol, in the presence of a catalyst, preferably ammonia, for the formation of an alcogel which is aged for approximately 10 days and washed with alcohol for removing water. The alcogel is thereafter treated in an autoclave by means of a temperature increase to above the critical point of the alcohol, isothermic pressure drop by means of the release of alcohol vapor, and temperature drop. The temperature increase, the pressure drop and the temperature drop take place at the such low mean rates that the aerogel does not crack. To this end, a total treatment time in the autoclave of at least 24 hours is required. After the autoclave treatment, a heat treatment at 500 DEG  to 750 DEG  C. is possibly carried out for further improving the transparency of the aerogel.

Abstract: A synchronous demultiplexer at a receiving station of a TDM/PCM telecommunication system, operating on an incoming bit stream organized in frames of 32 time slots of eight bits each, comprises a random-access memory having 32 cells loaded with consecutive octets in successive time slots under the control of a writing-address generator, stepped by clock pulses extracted from the bit stream, and unloaded at a similar but not exactly identical rate under the control of a reading-address generator, stepped by locally generated clock pulses. Two series of loading pulses a and b, each lasting for a bit period t, are derived from the extracted clock pulses near the beginning and near the end, respectively, of a time slot of duration T'=8t and are fed to a control unit together with a series of unloading pulses c of length 2t occurring once per cycle T'' APPROX T' measured by the local clock. The control unit normally selects loading pulses a for timing the transmission of writing addresses to the random-access memory, except when these loading pulses coincide with unloading pulses c which time the transmission of reading addresses to that memory; in the latter instance, loading pulses b are substituted for pulses a.

Abstract: The invention concerns a coupling, especially to facilitate the coupling of components which together create a column along which there is a movable boring tool. The coupling involves a male/female element presenting to each other interacting wedge surfaces (20, 21) which are moveable with respect to contact with each other primarily via the axial movement of the element relative to each other. The coupling involves a tool (37) which, by the dragging of the element forces the wedge surfaces into intimate contact with each other. A spring (29) is brought into the coupling which during the dragging of the coupling accumulates elastic force and thereafter tends to retain the contact between the element's wedge surfaces.<IMAGE>

Abstract: In a pneumatically powered rotating grinding machine there is provided a safety unit (13) comprising a speed governor and an overspeed release mechanism the purpose of which is to ensure a predetermined maximum speed. For safety reasons, the motor speed must never exceed a certain critical speed level which is determined by the mechanical strength of the working tool attached to the machine. When choosing a working tool to be attached to the machine the maximum speed mark of the machine is decisive. By having a portion of the safety unit exposed through an aperture (57) in the tool housing (10) and having the maximum speed mark (52) of the safety unit (13) located at the exposed portion, the maximum speed mark of the machine will always be the same as that of the safety unit (13). The suggested overspeed safety device avoids the risk involved in the event that a machine carrying a certain maximum speed mark might be erroneously fitted with a safety unit (13) intended for a higher maximum speed.
